EBS

EBS is an acronym that can refer to several concepts across different fields. The exact meaning usually depends on the context, and the term is most commonly associated with technology and public safety systems.

Elastic Block Store (EBS) is a cloud storage service provided by Amazon Web Services for use with its Elastic Compute Cloud (EC2) instances. EBS delivers persistent block storage that behaves like a hard drive attached to an instance. Volumes can be attached, detached, and reattached to instances, and data persists independently of the instance’s lifecycle. Features include encryption at rest, point-in-time snapshots to Amazon S3, and the ability to choose from different volume types to balance price and performance. Common types include general purpose (gp2/gp3), provisioned IOPS (io1/io2), Throughput Optimized HDD (st1), and Cold HDD (sc1). Pricing is typically based on allocated storage and IOPS/throughput, with performance varying by type and volume size.

Emergency Broadcast System (EBS) was a nationwide U.S. system intended to distribute emergency information to the public via radio and television. It was established in the 1960s and gradually superseded by the Emergency Alert System (EAS) in 1997, though the term remains part of historical discussions of broadcast-based emergency communication. The EAS integrated and expanded upon prior warning mechanisms, aiming to provide standardized alerts nationwide.

Electronic Braking System (EBS) refers to an electronically controlled braking framework used in some vehicles, particularly heavy-duty trucks and buses. EBS enhances braking performance by coordinating brake force at individual wheels through electronic control units, often in conjunction with ABS and stability-control systems. This setup improves control and stopping efficiency under various driving conditions.
